[tex] \sqrt{2.56} = 1.6 \\ \sqrt[3]{0.027} = 0.3[/tex]
1.6+0,3=1,8FAŁSZ
[tex] \sqrt{2 \frac{1}{4} } = \sqrt{ \frac{9}{4} } = \frac{3}{2} \\ \frac{3}{2} - \frac{1}{2} = 1[/tex]
PRAWDA
[tex] \sqrt{12} + \sqrt{27} + \sqrt{48} = \sqrt{4 \times 3} + \sqrt{9 \times 3} + \sqrt{16 \times 3} = 2 \sqrt{3} + 3 \sqrt{3} + 4 \sqrt{3} = 9 \sqrt{3} = \sqrt{81 \times 3} = \sqrt{243} [/tex]
PRAWDA
[tex]( \sqrt[3]{3})^{4} \times ({ \sqrt[3]{3} )}^{2} = ( \sqrt[3]{ 3})^{6} = 9[/tex]
